摘要： In a method to damp an oscillation of a roller driven via a drive in a printing system, a printing substrate web is directed across the roller, the roller and the printing substrate web forming a system capable of vibrating. With the drive the roller is driven with a predetermined nominal moment. With a sensor, a real value is determined of a variable representative of a velocity with which the printing substrate web is transported by the roller. In aid of a predetermined calculation rule, a correction moment is calculated from the determined real value such that a damping of the vibration-capable system results like a mechanical viscous damper. The correction moment is added to the predetermined nominal moment upon activation of the drive.
摘要翻译： 在通过印刷系统中的驱动器驱动的辊的振动的方法中，打印基材带材横跨辊子，辊子和印刷基材卷材，形成能够振动的系统。 通过驱动，辊子以预定的标称力矩驱动。 使用传感器，确定代表速度的实际值，印刷基材幅材通过该速度由辊输送。 借助于预定的计算规则，根据所确定的实际值计算校正力矩，使得可振动系统的阻尼如机械粘性阻尼器那样产生。 在驱动器启动时，校正时刻被加到预定的标称时刻。

摘要： A graphic arts sleeve includes a cylindrical plate presenting an outermost sleeve surface operable to engage and thereby texture, print, and/or hot foil stamp on a substrate. The cylindrical plate presents an innermost support surface opposite the outermost sleeve surface and operable to engage a mandrel. The cylindrical plate includes an intermediate carrier layer and an overlying engravable layer cladded to and supported by the carrier layer. The cylindrical plate further includes an underlying expansion layer cladded to the carrier layer. The expansion layer has a greater coefficient of thermal expansion than the carrier layer, with heating of at least the expansion layer causing diametrical expansion of the innermost support surface to facilitate mounting or removal of the cylindrical plate relative to the mandrel.

摘要： A printing technology wherein an endless belt-shaped printing plate is wound about a plate cylinder and a guide roller of a printing cylinder and, by using the printing plate, a continuous form sent between the printing plate and an impression cylinder is printed. In the plate cylinder, feed pins are disposed in rows at an even pitch along an outer periphery of the cylinder. The feed pins are guided by a fixed cam ring and project and retract freely and project in a desired region of the plate cylinder, respectively with respect to the cylinder surface. Pin feed holes are provided in rows in marginal zones of the endless belt-shaped printing plate. The endless belt-shaped printing plate is formed by joining and bonding both ends of an elongated resinous relief printing plate with an adhesive tape from the printing surface side. The pin feed holes are engaged with the feed pins of the plate cylinder, whereby the plate feed is guided.

摘要： Systems and methods for allowing existing rotary printing press units to produce smaller pages at a faster rate of speed without having to replace the press unit. Specifically, the systems and methods relate to retrofitting an existing press unit to produce three pages of material in each full rotation instead of the traditional two pages.

摘要： An adapter sleeve has an external layer for supporting a printing cylinder carrying data and/or images to be printed. The adapter sleeve has an internal layer defining a bore enabling the sleeve to be mounted onto a rotary mandrel of a printing machine. Each opposite extreme end of the adapter sleeve includes a rigid, load-bearing, radial spacer member disposed between the layers to provide rigidity and indeformability during the use of the sleeve with time. The inner surface of each of the extreme end radial spacer members is defined by rigid and non-deformable material of very low coefficients of dynamic and static friction.

摘要： A rubber sleeve for a printing press and a method for producing a rubber sleeve is disclosed. The rubber sleeve has a rigid support sleeve and a blanket that is wrapped around the support sleeve as well as is firmly connected to the support sleeve. The blanket has at least a two-layer structure with an inner layer embodied as a base layer and an outer layer serving as a functional layer for the printing process, where the butting edges of the blanket are connected to one another via a sealing material, which is introduced in a gap embodied between the butting edges. The sealing material is introduced in the gap embodied between the butting edges while forming a channel.
